Title: Apparatus for handling elongated masses of material
IPC: B65G47/52
Filed: 1973-09-06
Abstract: 1415606 Conveyers CHEMETRON CORP 6 Sept 1973 [28 Sept 1972] 41918/73 Heading B8A Apparatus for handling elongated loaves 509 of luncheon meat, cheese, sausage etc., comprises a rollerway 520 for feeding an elevator 36, 526; and a driven roller conveyer 512 which transfers the loaves from the elevator to a shoot 554 provided with rollers 188. A pair of rotary knives 558 cuts off the rounded ends of the loaves while the latter are on the elevator. The inclination of the rollerway 520 is adjustable and a section 16 has rollers 21a supported in cantilever fashion to enable fingers 24 attached to a lift bar 26 of the elevator to pass between groups of the rollers. The bar 26 is guided between two webs 34 of the elevator framework which pivots between the positions shown in Fig. 2, the bar 26 being raised and lowered by a chain 70 reversibly driven by a motor 536. A motor-driven crank unit 100, 552, 110 causes the elevator framework to pivot. The roller conveyer 512 has pairs of tapered rolls 130 driven by a belt 134 engaged by resilient pinch rolls 136. The shoot 554 is adjustable for height and angular position and has adjustable guide walls 194. The loaves 509 are fed side-by-side to a stop 20 at the end of the rollerway section 16 from which individual loaves are raised by the elevator fingers 24. After the loaf ends have been cut and the loaf raised to the top of the elevator, the latter pivots to its full-line position, Fig. 2, and the loaf is lowered on to the roller conveyer 512 for transfer to the shoot 554. The taper on the rolls 130 tends to prevent the loaf from falling off the ends of the rolls. When the lif bar 26 has been completely lowered the elevato framework returns to its inclined position ready to lift the next loaf. Figs. 4, 5, 6 (not shown) are concerned with electric power and control circuitry and with the positioning of limit switches for controlling the sequence of operations of the apparatus.

Abstract: 1,248,020. Toothed gearing. GENERAL MOTORS CORP. 3 Sept., 1970 [8 Sept., 1969], No. 42257/70. Heading F2Q. Noise from a thin-webbed gear pinion 14 is reduced by subjecting the pinion to axial loading from a prestressed Belleville spring washer 31, the periphery of which engages the outer face of the pinion adjacent its teeth 18. As shown, the spring loading is adjustable by an axial bolt 36, but this may be effected by a spring snap ring and adjustable shims. A similar spring may be fitted on the opposite face of the pinion abutting the bearing 11, this spring acting alone or in conjunction with spring 31.

IPC: F04C14/26
Filed: 1962-11-08
Abstract: 1,004,007. Rotary pumps. FERRY-DIAMOND ENGINEERING CO. Ltd. Oct. 31, 1963 [Nov. 8, 1962], No. 42290/62. Heading F1F. In a rotary pump of the flexible vane type driven by an electric motor 2, Fig. 1, a separable sealing housing 14 is fitted in that end of the pump chamber 5 adjacent the motor. The housing 14 may be formed with a tongue 15, Fig. 3, to form a segment against which the vanes of the impeller 24 are deformed and is located in the pump chamber by a groove 17 and a pin 16 between the suction and delivery ports 12, 13. The housing 14 is fitted with a shaft seal 21 loaded by a spring 22 and an 0-ring 20. The spring 22 besides loading the shaft seal, on removal of the cover plate 25 urges the impeller 24 and the sealing housing 14 outwardly so that they can easily be removed from the pump chamber for cleaning, renewal or inspection. The segment 15 instead of being part of the seal housing 14 may be a separate removable part or be part of the cover plate 25. A groove cut around the pump chamber between the suction and delivery ports permits the by-passing of a small quantity of liquid to lubricate the pump during limited periods of dry running. Alternatively a nozzle with a restricted opening may be fitted in a flexible line between the ports externally of the pump body to recirculate the liquid during dry running periods and also avoid operating the pump against excessive pressure.

Title: Apparatus for controlling motors operable by fluid under pressure
IPC: E21C35/04
Filed: 1959-12-16
Abstract: 924,505. Mineral-mining machines. EICKHOFF MASCHINENFABRIK U. EISENGIESSEREI m.b.H. GEB. Dec. 16, 1959 [Dec. 24, 1958], No. 42707/59. Class 68 (1). [Also in Group XXIX] Apparatus for controlling a fluid-operated motor, such as a motor 7 arranged to drive the haulage device of a coal-getting machine, comprises a valve 10 adapted to open when the pressure in a pipe 4 between a source 1 of fluid pressure and the motor rises to a predetermined value and to remain open when the pressure has fallen below the predetermined value. The source of fluid pressure may be a vane-type pump 1 having the eccentricity of its rotor 2 controlled by a cam 3 to vary the output of the pump which is connected to the pipe 4 leading to a valve 6 controlling the flow of fluid to the motor 7, which may drive the winch of the machine, or a motor 8, which may move a swinging jib or other device. The pipe 4 is provided with a one-way valve 5 and is connected by a pipe 9 to the valve 10 which has a stepped piston 11 urged by a spring 12 to a position closing an exhaust passage 13. The pressure in the pipes 4 and 9 acts on the smaller portion of the piston and when the pressure rises to a predetermined value moves the piston against the spring 12 to the right. The pressure can then act on the larger portion to move the piston rapidly and open the passage 13, the pressure acting on the larger portion maintaining the valve open at pressures below the predetermined value. The one-way valve 5 prevents a rapid fall of the pressure in the motors which may operate slowly until the pressure therein is reduced by leakage. The passage 13 can only be closed by adjusting the cam 3 of the pump to reduce the output pressure to a value which will permit the spring 12 to return the piston 11 to its original position. The arrangement prevents excessive pressure in the system and consequential raising of the temperature of the fluid. An arrangement is referred to in which a pressure-relief valve is provided in the fluid circuit and allows the pressure in the circuit to act on a piston connected to the rotor or stator of the pump.

[Also in Divisions A1, E1 and G1] In an earth excavating machine having an earth-excavating tool 10 carried by a framework 11 which is vertically movable, a grading device GD comprises two or more vertical tubes which are interconnected and partially filled with a liquid, the tubes being positioned on the framework 11 and so set astride the vertical median-plane of the tool 10 as to ensure that the liquid always remains at a theoretical static level relative to the tool, and at least a part of one of the tubes being transparent so that the liquid level provides a sighting datum for correlating with ranging rods set up ahead of the machine. The device preferably has two laterally spaced sighting perspex tubes 14, 15 interconnected by tubes 18 with two compensating longitudinally spaced steel tubes 16, 17, and the liquid is engine oil. A bottle is connected to the tubes 18 through a tap, the arrangement being such that the liquid level in the tubes can be adjusted. The upper ends of the tubes 14 ... 17 are also interconnected by tubes having an air vent therein. The relative cross-sectional areas of the tubes depending on their distance from the vertical median plane of the tool are chosen to ensure that the liquid level is constant at the said plane. A secondary set of tubes may be provided, Fig. 9 (not shown), and partially filled with a liquid which is different in colour from that in the device GD. The tubes are arranged so that the level of the liquid is the same as that of the device GD, and in operation the sighting liquid levels which are separated longitudinally of the machine are aligned with a sight line whereby the tool is kept at the correct height to maintain a true predetermined grade. The tool may be a digging wheel, a bulldozer blade, a mole plough or drainer, e.g. a plough having a vertical knife behind which is a round or tapered mole, or a bucket chain, and the machine may be adapted to lay tiles or a continuous length of plastic pipe in a trench.
